Determining the Software Version
Note We strongly recommend that you use the latest available software release for all Cisco MDS 9000 Family products.
To determine the version of the Cisco SAN-OS software currently running on a Cisco MDS 9000 Family switch, log in to the switch and enter the show version EXEC command.
This Cisco MDS SAN-OS Release 1.1(1a) software is packaged in feature sets (also called software images) depending on the platform. The Cisco MDS SAN-OS software feature sets available for the Cisco MDS 9000 Family include Ethernet, Fibre Channel (1 Gbps and 2 Gbps), SNMP, and IP packets.
Table 3 lists the compatible matrix for Cisco MDS SAN-OS releases.
New Features in Release 1.1(1a)
SAN-OS Release 1.1(1a) is a maintenance release for switches in the Cisco MDS 9000 Family. See the "Caveats" section for details on closed and outstanding caveats and limitations.
Limitations and Restrictions
The following limitations and restrictions apply to all switches in the Cisco MDS 9000 Family:
Downgrading to 1.0(4) or to 1.0(3a) from Release 1.1.1a
When downgrading the following switches from Release 1.1(1a) to Release 1.0(3a) or to Release 1.0(4), avoid using the reload command:
•Cisco MDS 9216 switches
•Switches in the Cisco MDS 9500 Series with only one supervisor module.
Caveat CSCea76574 already addresses this limitation.
Tip Use the install all command to gracefully reload the switch and handle configuration conversions.
To revert to Release 1.0(4) or 1.0(3a) from Release 1.1(1a), follow these steps:
Step 1 Save the configuration using the copy running-config startup-config command to save the new configuration into nonvolatile storage.
Step 2 Issue the install all command to reload the switch.
Refer to the Cisco MDS 9000 Family Configuration Guide for further information on the install all command.
Caveats Resolved in Release 1.1(1a)
The following caveats were resolved in Release 1.1(1a):
This section lists the caveats and corrected caveats for this release. Use Table 4 to determine the status of a particular caveat. In the table, "R" indicates a resolved caveat, and "O" indicates an open caveat.
Table 4 Release Caveats and Caveats Corrected Reference
DDTS Number Software Release (Resolved or Open) 1.1(1) 1.1.(1a)
Symptom: An E port remains in offline mode after a switch is reloaded.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb36501
Symptom: The Fabric Manager topology map incorrectly shows links between switches resulting from duplicate domain IDs in two or more VSAN islands.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb07573
Symptom: Reverting to Release 1.0(3a) or to Release 1.0(4) from Release 1.1(1a) using the reload command causes the Zone server to crash. This occurs on Cisco MDS 9216 and 9500 with a single supervisor (see the "Downgrading to 1.0(4) or to 1.0(3a) from Release 1.1.1a" section).
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea76574
Symptom: An alert (syslog error notification, SNMP trap, or Call Home message) is not generated if the standby supervisor module fails to bootup properly.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb25354
Symptom: The switch port did not perform link reset to recover from an all credit lost state on E and TE ports.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb32230
Symptom: Issuing a show system switchover impact command while any module is booting up causes a Cisco MDS 95095 switch to failover.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb10177
Symptom: During switch bootup, occasionally some modules may fail to come online and may report the following syslog message: XBAR-2-MOD_CONNECTION_FAILURE: Xbar connection with module x failed
XBAR-1-XBAR_ASIC_FATAL_ERROR: Encountered Fatal ASIC Error for module x device 12 error 0xc02
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb32430
Symptom: If automatic image synchronization is enabled, and the standby supervisor module is synchronizing the image from the active supervisor, the switch will not stop you from issuing the reload command on the active or standby supervisor modules. This may result in a failure to synchronize the images.
Workaround: Be sure to allow sufficient time for the images to be synchronized before reloading a supervisor module. Use the show system status redundancy CLI command to check the standby supervisor status.
Symptom: When you issue the copy startup-config running-config command on a switch which is already up and running, the trunking ports may flap, due to reapplication of allowed VSANs for trunking ports in the startup configuration.
Workaround: Ensure that the startup configuration does not contain any allowed VSAN configuration for trunking ports (trunking ports default to the allowed VSAN configuration).
Symptom: After issuing the fcdomain manager restart disruptive command, an IBM tape 3590 port on the switch displays a not connected status.
Workaround: Bring up the port by issuing the shut command followed by the noshut command on that port. For example:switch# config tswitch(config)# int fc1/1switch(config)# shutswitch(config)# no shut
Symptom: If a copy running-config startup-config command is issued when a switching module is temporarily down, the configuration for that module will be deleted from the system. This primarily occurs at boot time before all the modules are online.
Workaround: First issue the show module command to ensure that all modules are online before issuing a copy running-config startup-config command.
Symptom: Avoid using the same TCP port number for iSCSI and FCIP protocols on an IP Storage Services module (IPS module) port.
Symptom: Importing the ASCII configuration multiple times in the same switch can cause the FCIP interface to go into error disabled state.
Symptom: When the Fabric Manager or Device Manager communicates with the Cisco MDS switch through Virtual Private Network (VPN) or any Network Address Translation (NAT) scheme, a generic error message occurs while adding duplicate zone members from a VPN connection.
Workaround: None. If an error occurs while running through VPN/NAT, all errors will show up as generic errors without a detailed message describing the error.
Symptom: The Fabric Manager or Device Manager reports an error for all operations if the switch is multihomed (both IPFC-based in-band management and the out-of-band management interface are up) and the Fabric or Device Manager was started using the IPFC address. Typically, you will see a notInTime window error in the Device Manager and all SNMP set operations fail.
Workaround: If the switch is multihomed, then start the Fabric or Device Manager on the switch using the out-of-band management interface IP address.
Symptom: The followingIPS module port configurations are not allowed:
–If a member port has subinterfaces, then the member port cannot be added to any PortChannel.
–If a member port is part of a PortChannel, then you cannot create subinterfaces in this member port.
–If a Gigabit Ethernet port is part of a PortChannel, then you cannot create a different PortChannel on its adjacent port.
Workaround: Do not perform these PortChannel related configurations. If you do have one of these configurations, remove it.
Symptom: For iSCSI configurations, both no pwwn hh:hh:hh:hh:hh:hh:hh:hh and no pwwn auto number delete all the pWWNs for a given target.
Symptom: If you change the iSCSI switchport identification from name to IP address, the TCP sessions are not terminated.
Symptom: The Fabric Manager and Device Manager do not support iSCSI TCP parameter configuration and display.
Symptom: When you delete a pWWN for an auto-created iSCSI initiator using the Device Manager, (removed from snmp fcAddress table), it still shows up in the CLI (the initiator is still auto-created).
Symptom: The counter values freeze if the Device Manager port monitor window has been up and running for a long time (overnight or a few days).
Workaround: Close the frozen Device Manager window and re-open Device Manager.
Symptom: The Device Manager shows a port in the down state (red square) when the operational status of the port is up. This rare occurrence is due to the failure cause of the port not being empty (for example, the failure case reflects the initializing state).
Symptom: When a switch is upgraded while the Device Manager for that switch is open, a Java error of class cast exception occurrs. When this error occurs, some Device Manager menu items are unusable while other menu items remain in this error state.
Workaround: Close the Device Manager and reopen it.
Symptom: After plugging and unplugging a Gigabit Ethernet cable multiple times the PortChannel gets isolated and issues a remote domain manager not responding error.
Symptom: Sometimes, the zone merge import command results in isolation.
Workaround: Reissue the command to resolve the isolation problem.
Symptom: The following error message is issued when you try configuring switch drop latency:changing this parameter is not allowed could not update the value
Workaround: None. Switch drop latency is not configurable in this release of the software.
Symptom:The Telnet server may not be disabled even if you disable it through setup. A telnet session will still work in the switch.
Workaround: Issue the no telnet server enable command in configuration mode to disable telnet after you login to the switch.
Sympton: An error message in the log file occurs because the platform manager component passes the wrong parameter while responding to a SNMP query. In some cases, this results in the query not being responded to.
Workaround: Perform a refresh on Device Manager to clear the problem.
